What does 'moly faced' mean for these piston rings?

Moly faced means the rings have a coating of molybdenum compound. This coating helps them wear better, handle more heat, and seal more effectively against the cylinder wall.

What does the '.050in' in the product name signify?

The '.050in' indicates that these are oversized piston rings. They are designed to fit cylinders that have been bored out by 0.050 inches larger than their original size.

Are these rings compatible with all Big Twin engines from 1966-1984?

These rings are specifically designed for Big Twin (BT) engines within the 1966-1984 model years. It's always best to confirm your specific engine application matches the manufacturer's fitment details.

About this part

Product Details

These S&S Cycle piston rings are moly faced, meaning they have a coating of molybdenum compound. This advanced coating is known for improving wear resistance, handling higher heat, and creating a better seal between the piston and cylinder wall. This is a .050 inch oversized set, designed for Big Twin engines from 1966-1984.

When you're rebuilding an engine, the piston rings are critical for proper compression and oil control. The moly facing on these rings helps them hold up better over time and under demanding conditions, contributing to a more reliable rebuild. They fit right into the groove on your piston, and the .050 inch oversize is important to note if you're matching them to a specific bore size.
